Abstract: Methods are provided for providing novel flexible hose constructions. In one embodiment, the improvement includes the steps of forming an inner corrugated hose of polymeric material to have a plurality of outwardly convex projections with recesses therebetween, then disposing an outer sleeve of reinforcing material in telescoping relation on the inner hose, and then disposing an outer sleeve of polymeric material in telescoping relation on the sleeve of reinforcing material. A tube of polymeric material is disposed between the sleeve of reinforcing material and the inner hose by extruding the tube onto the inner hose before disposing the sleeve of reinforcing material thereon. The inner hose is formed with an outer layer of one thermoplastic material and an inner layer of a different thermoplastic material. The tube is formed from the same thermoplastic polymeric material that forms the outer layer of the inner hose. The outer sleeve is formed of the same thermoplastic polymeric material that forms the tube by the steps of extruding to cause the tube to be bonded to the projections of the inner hose. The bonding of the sleeve of polymeric material is caused to be bonded to the tube of polymeric material through the sleeve of reinforcing material by extruding the sleeve of polymeric material onto the sleeve of reinforcing material. One embodiment of the flexible hose construction of this invention comprising an inner corrugated hose which is made of polymeric material and which has a plurality of outwardly convex projections with recesses therebetween which extend from one end thereof to the other end thereof. An outer sleeve of reinforcing material is disposed in telescoping relation on the inner hose, and a tube of polymeric material is disposed between the sleeve of reinforcing material and the inner hose and extends into a generally-straight-line manner from projection to projection of the inner hose. In this way the flexibility characteristics of the inner hose is not substantially reduced.

Title: Biosensing instrument and method
Inventor: WHITE BRADLEY E
IPC: G01N33/487
Filed: 1990-12-14
Granted: 1999-03-30
Abstract: A  biosensing  system  is  described  which  determines whether a measured current is varying  in accordance with  a  predetermined  Cottrell  current  relationship. The system includes a test cell with at least a pair of electrodes which extend into a reaction zone,  which reaction zone includes analyte reactants.   An analog signal detector, in combination with a microprocessor, take  plurality  of  current  measurements  between  the electrodes over a plurality of succeeding measurement times,  after a sample is placed in contact with the analyte   reactants   in   the   reaction   zone.    The microprocessor also stores a plurality of succeeding comparison constants which are derived by taking the inverse ratio of the square root of a measurement time divided by the square root of a subsequent measurement time.  The microprocessor selects a pair of succeeding measurement times;  derives a  ratio of  the  currents measured at those times; and then compares the ratio of those currents with the comparison constant previously derived for the pair of succeeding measurement times. If the comparison indicates that the measured current ratio is dissimilar from the comparison constant,  an indication is developed that the current between the electrodes  is  not  varying  in  accordance  with  the Cottrell relationship.       The plurality of current measurements are also used to calculate total charge transferred, Q.  Q can then be used as a second means of calculating the final result.

Granted: 1996-03-26
Abstract: An ultrasonic processing method and apparatus are disclosed wherein during the processing time interval the motional amplitude of the resonating horn and thereby the power to the workpiece is changed responsive to the production of a control signal.  The control signal is process related and generated, in a typical example, when there is sharp rise in the power curve.          In another example, the power is changed responsive to a changing dimension of the workpiece.  In typical examples, the control signal reduces the motional amplitude for the remaining time interval.
